Ukufezekisa iNtsebenzo eKhethekileyo: Ukuqonda iiMfuno ze-Roller Coating ze-Aluminium Coil

Intshayelelo:

I-roller coating ibe yindlela ekhethiweyo yokufaka iingubo kwiikhoyili ze-aluminium ngenxa yokusebenza kwayo kunye nokusebenza kwayo.Ngokunyuka kwemfuno yomgangatho ophezulu kunye nokuqina kweemveliso ze-aluminiyam ezigqunywe nge-aluminiyam, ukugquma kwe-roller kube yinkqubo ebalulekileyo kwishishini le-aluminium.Nangona kunjalo, ukuze ufezekise iziphumo ezinqwenelekayo, kubalulekile ukuqonda iimfuno ezithile zokusebenza zokwaleka kwe-roller.Kule bhlog, siza kuphonononga kwiimfuno eziphambili zokusebenza ekufuneka zifezekiswe ziingubo zokwaleka, sigxile kwi-viscosity kunye neempawu zokulinganisa, ukunyanga okukhawulezayo, iimpawu zokuhombisa, kunye nokumelana nemozulu.

1. I-viscosity efanelekileyo kunye neempawu ezintle zokulinganisa:

Inkqubo yokugubungela i-roller ibandakanya ukondla kwebhanti ngokukhawuleza, ukugquma kwe-roller, ukubhaka okuphezulu kweqondo lokushisa, kunye nokupholisa ngokukhawuleza.Ukuqinisekisa iipropathi ezifanelekileyo zokulinganisa, kubalulekile ukuba i-roller yokugqoka ifake inani elaneleyo lepeyinti kwizinto ze-aluminium.Ke ngoko, iingubo zokwaleka eziqengqelekayo kufuneka zibe ne-viscosity efanelekileyo kunye neempawu zomgangatho olungileyo.I-viscosity yokwambathisa kufuneka iqulunqwe ngononophelo ukuvumela isicelo esilula ngelixa igcina ukukwazi kwayo kwinqanaba elilinganayo kumphezulu we-aluminium.Ukufezekisa ulungelelwaniso olufanelekileyo lwe-viscosity lubalulekile ekuthinteleni imiba efana nobukhulu obungalinganiyo bokugquma, imivimbo, kunye neziphumo zamaxolo e-orenji.

2. Ukunyanga ngokukhawuleza:

Ngenxa yendalo ekhawulezayo yemigca yokuvelisa i-roller coating, ukunyangwa ngokukhawuleza kuyimfuneko ebalulekileyo kwiingubo zokugqoka ii-roller.Ngaphandle kwenkxaso kunye nobude obunqamlekileyo be-oven yokubhaka, ixesha elikhoyo lokupeyinta ukunyanga liyancipha kakhulu.Iipeyinti ezisetyenziswe kwi-roller coating kufuneka zenziwe ukuba zinyange ngexesha elifutshane, ngokukodwa ngaphantsi kwemizuzwana engama-60.Ukongeza, inkqubo yokunyanga kufuneka igcine ipeyinti ingaphantsi kobushushu bekhoyili ye-260°C ukuthintela ukuguqulwa kwezinto okanye ezinye iimpendulo ezingathandekiyo.Ukukhetha okufanelekileyo kwesinyibilikisi kuyafuneka ukufezekisa ukunyangwa ngokukhawuleza ngaphandle kokubeka esichengeni isidima sengubo, ukuthintela imiba eqhelekileyo efana nokubhubhudla, imingxunya, kunye nomgangatho ombi.

3. Iimpawu zokuhombisa:

Ngaphandle kweempawu ezisebenzayo, iingubo zokugqoka ii-roller kufuneka zihlangabezane neemfuno zokuhombisa.Ipeyinti yepolyester ihlala yanele ukufezekisa ukubonakala okufunwayo kunye nesicelo esisodwa.Nangona kunjalo, xa usebenzisa i-fluorocarbon coating, i-primer kunye ne-topcoat iyimfuneko kwiziphumo ezifanelekileyo zokuhombisa.I-primer kufuneka ibe nokumelana nokugqwesa okugqwesileyo kunye nokunamathela kuzo zombini i-substrate kunye ne-topcoat, ngelixa i-topcoat kufuneka ibonise amandla amahle okufihla kunye neempawu zokuhombisa.Ingubo enye ye-primer elandelwa yingubo enye ye-topcoat inokubangela ukubonakala okuhle okuhlangabezana neemfuno zobuhle kunye nokusebenza.

4. Ukuxhathisa imozulu:

Iingubo zokwaleka eziqengqelekayo kufuneka zibonise ukuxhathisa okukhethekileyo kwemozulu, ngakumbi xa zifakwa kwiimveliso ze-aluminiyam yangaphandle.Iingubo ze-PVDF ze-fluorocarbon zidla ngokusetyenziswa ukunika ukusebenza okubanzi ngokuchasene nezinto ezifana nokuqina, imvula eneasidi, ungcoliseko lomoya, umhlwa, amabala amileyo, kunye nokungunda.Ngokuxhomekeke kwiimfuno zendawo ethile, iidyasi ezimbini, ezintathu, okanye ezine zePVDF zingafakwa.Oku kuqinisekisa ukukhuselwa okuhlala ixesha elide kunye nokuqina okuphezulu, ukuvumela i-coil ye-aluminiyam egqunyiweyo ukuba imelane neemeko ezinzima zokusingqongileyo.

Isiphelo:

Ukuqukumbela, ukufezekisa ukusebenza okungaqhelekanga kokwaleka kwe-roller kwiikhoyili ze-aluminium kufuna ukuqwalaselwa ngononophelo kwe-viscosity yokwaleka kunye neempawu zokulinganisa, ukukwazi ukunyanga ngokukhawuleza, iimpawu zokuhombisa, kunye nokumelana nemozulu.Ngokuqonda kunye nokuthobela ezi mfuno zokusebenza, abavelisi banokuvelisa iimveliso ze-aluminiyam ezikumgangatho ophezulu ezihlangabezana nemigangatho efunekayo kumashishini ahlukeneyo.Njengoko imfuno yeekhoyili ze-aluminium ezithembekileyo nezibukekayo ziqhubeka zikhula, kubalulekile ukubeka phambili ukhetho kunye nokusetyenziswa kweengubo zokugqoka ezinokuthi zizalisekise ezi mfuno zokusebenza ezibalulekileyo.
